problem "same name are not supported" c # [closed]

Good people I have a problem to be programming in C# to fill the form of poles I get an error

Code

using System;
using MySql.Data.MySqlClient;
using System.Windows.Forms;
using System.Data;

namespace CapaDatos{

    public class IngresoPoste {
       private dbConxion conexion2 = new dbConxion();
          MySqlCommand comando2 = new MySqlCommand();
          public void agregarPoste(String codPos1, String tipRed1, 
                                   String mater1, String estado1,
                                   String direc1, String propi1, 
                                   double puntoX1, double puntoY1, 
                                   String fot11, String fot21, 
                                   String fot31, String obs1)
        {
            try
            {
                comando2.Connection = conexion2.AbriConexion();
                comando2.CommandText = ("proc_insertar_poste");
                comando2.CommandType = CommandType.StoredProcedure;
                comando2.Parameters.AddWithValue("@codPos", codPos1);
                comando2.Parameters.AddWithValue("@tipRed", tipRed1);
                comando2.Parameters.AddWithValue("@mater", mater1);
                comando2.Parameters.AddWithValue("@estado", estado1);
                comando2.Parameters.AddWithValue("@direc", direc1);
                comando2.Parameters.AddWithValue("@propi", propi1);
                comando2.Parameters.AddWithValue("@puntoX", puntoX1);
                comando2.Parameters.AddWithValue("@puntoY", puntoY1);
                comando2.Parameters.AddWithValue("@fot1", fot11);
                comando2.Parameters.AddWithValue("@fot2", fot21);
                comando2.Parameters.AddWithValue("@fot3", fot31);
                comando2.Parameters.AddWithValue("@obs", obs1);
                comando2.ExecuteNonQuery();
            }
            catch (Exception ex) {
                MessageBox.Show("ocurrio un error--->"+ex.Message);
            }
        }
    }
}

Well what I'm doing is a program that consists of three layers one has the database connection of MySql and as you can see I'm calling the database in conexion2 to call a procedure and what store, but I get the error

  

same name are not supported
